Motion In Straight Line

Question

Wired Faculty App

A body is whirled in a horizontal circle of radius 25 cm. It has an angular velocity of 13 rad/s. What is its linear velocity at any point on circular path?

2 m/s

3 m/s

3.25 m/s

4.25 m/s

Solution

C.

3.25 m/s

Given:- r = 25 cm = m

ω = 13 rad/s

Linear speed = Radius × angular speed

V = rω

= 0.25 × 13

3.25 m/s
